Abstract: A measuring device for hollow cylindrical surfaces, such as bores and the like, comprises a housing to be fixed in the bore by clamps, a measuring arm rotatable by a first step motor, a measuring head axially movable along the measuring arm substantially parallel to the axis of the bore surface by a second step motor and a sensor incorporated in the measuring head and radially movable relative to the measuring head against the force of a leaf spring in contact with the bore surface. The leaf spring supports strain gauges, the output signals of which are representative of the radial or transverse paths of the sensor and thereby for the shape of the bore surface to be measured.

Abstract: The present invention relates to a method and apparatus for detecting the geometrical features of mechanical workpieces, particularly for measuring eccentricity and out-of-roundness of cylindrical and revolution surfaces in which at least two size checks on relevant sections of the cylindrical surface and at least two size checks on the same section of the revolution surface are carried out and the data resulting from the checks are processed to supply an indication of the eccentricity of the two surfaces and of the roundness of the section of the revolution surface. The apparatus includes a plug carrying feelers which is automatically positioned with respect to a workpiece and then revolved, so that feelers carry out measurements. The apparatus is used for checking valve guide holes and valve seats of engines and similar workpieces.

Abstract: A measuring device for checking mechanical pieces either while stationary or rotating which includes a first feeler substantially fixed with respect to a support and in alignment with a measuring head having a second feeler and supported by the support, a commutation unit containing a shaft and cams for changing the support and an electrical unit for detecting and visually recording the diameters and geometrical errors. In a first working condition the support of the measuring device can oscillate in order to allow both the first and second feeler to remain in contact with the piece to be gauged. The commutation unit allows for a change from the first working condition for measuring diameters of the work piece through the first and second feelers to a second working condition for measuring geometrical errors of a piece through the second feeler.

Abstract: A coordinate measuring machine for measuring coordinates or properties of a workpiece includes an extended stylus. The extended stylus includes an extension element and a connection element. The extension element includes a carrier portion mounted at the connection element so as to be rotatable about an axis of rotation. The extension element includes, on a side remote from the connection element, a shaft portion that is aligned so as to deviate from the axis of rotation. The coordinate measuring machine includes a measurement head to which the extended stylus is attached. The measurement head is configured to measure deflections of the stylus resulting from contacts of the extended stylus to the workpiece.

Abstract: A shaft roundness gauge measures the roundness (or lack thereof) of a surface such as a bearing surface of a shaft or axle of a truck, tractor or trailer. The gauge comprehends a plurality of specifically sized rings or collars having inner diameters which correspond to common outside diameters of shafts, axles and other circular or cylindrical components. The ring includes a radial opening which receives a collet fitting which receives a probe housing of a dial indicator. A collet clamp may be tightened to secure the dial indicator to the ring. The ring and dial indicator are positioned on a shaft, at that position where the shaft or component is believed to be least worn. The dial indicator is zeroed and then the assembly is rotated around the shaft or component to determine, by the reading of the dial indicator, the location of and the extent of wear of the shaft or component.
